Becoming a victim of ransom-ware is now a common occurrence, Fake phishing emails with attachments containing malicious code are an everyday item in your inbox. and its very easy to misread something or click a link by accident, to contract the virus.
Ransom-ware shortened from ransom software encrypts information on your PC and network, basically anything your PC can see it can infect, such as mapped network drives, USB devices and online storage services like Dropbox. The software encrypts or scrambles the information making it unreadable by standard software, it does this in a way that makes decryption of the file or information virtually impossible, due to the sheer complexity of the encryption type used. This in some cases is greater than the level used in the banking industry and is classed as military level. The only way to recover the file is with the passphrase or key, which is where the ransom aspect comes in, as you dont get the key unless you pay a significant amount for it. Even then it is no sure guarantee to recover your files.
